Introduction

The LSST Software Stack (LSST Stack) is the collection of source code used to process LSST data and generate the official output data products. The stack includes the applicationlayer (the image processing software to detect and characterize sources on images, detect moving objects, build co-added images, difference images, etc.), the middlewarelayer that includes both pipeline and orchestration components that manage the robust execution of the application code on large clusters with thousands of cores, and the distributed database to store and serve the resulting catalogs. Note: the distributed database will soon be replaced by qserv.
